kotlin - 用 mockk 模拟私有(private)属性(property)抛出异常

Question

我正在使用 mockk用于我在 kotlin 中的测试。但我似乎无法覆盖 spy 对象中的私有(private)属性。

我有这个对象

private val driverMapSnapshotMap: MutableMap<Int, SnapshotImage> = mutableMapOf()

在我监视使用的类(class)中

viewModel = spyk(DriverListViewModel(), recordPrivateCalls = true)

但是当我试图让它充满模拟值时，我得到一个错误

every {
    viewModel getProperty "driverMapSnapshotMap"
} returns(mapOf(1 to mockkClass(SnapshotImage::class)))

我得到的错误

io.mockk.MockKException: Missing calls inside every { ... } block.

有什么想法吗？

It is nearly impossible to mock private properties as they don't have getter methods attached. This is kind of Kotlin optimization and solution is major change.
